摘要

森林生态系统价值尚未形成成熟的评价方法.谢高地等基于Costanza的方法创建了当量因子法

中国林业科学院森林生态环境与保护研究所创建了LY/T1721-2008评估规范.以安徽池州市境内的秋浦河河源森林生态系统为例

以2007年为基准年

用两种方法计算其生态服务价值分别为11 330.92

49 369.59万元.创建背景不同

方法不同

指标类型以及参数选取不同等是导致评估结果相差甚远的主要原因.当量因子评估法依条件价值法为机理而创立

较客观地体现了人们的主观支付意愿

但粗略、宽泛;LY/T1721-2008评估法测重于理论研究

细致、准确但离人们的支付意愿相差较大.

Abstract

Currently a satisfying evaluation method has not been developed for the forest ecosystem evaluation yet.Based on the Costanza's method

XIE Gao-di introduced the equivalent weight factor method.In 2008

the Institute of Forest Eco-environment and Protection

Chinese Academy of Forestry promulgated the evaluation criterion of forest ecosystem(LY/T1721-2008).Taking the riverhead forest ecosystem of Qiupu River in Chizhou City

Anhui Province as an example

the two methods were applied to calculate the service value of the forest ecosystem as approximate-ly1.13×108Yuan and 4.94×108Yuan

respectively

in 2007.This large disagreement between two numbers could be attributed to the background behind which the methods were created

different concepts

index types and included parameters.Equivalent weight factor method was created based on conditional values

reflecting objectively the people's willingness to pay(WTP).However

it maybe not theoretically precise.LY/T1721-2008assessment method emphasizes more on theoretical application and is therefore more precise and accurate.However

its results may deviate considerably from the people's willingness to pay.
